Discussions of the methods of fabric spreading’s.



Fabric spreading is so much important part of a garments industry to cut the fabric and sewing properly and proper shape. After spread the fabric, it’s ready to cut and make them desire look. Without spreading fabric not possible cut so many pieces of cloth at a time which way is important in garments industry.

Basically most of the fabric are import in garments industry in a few different package and roll shape. Those fabric roll and package are unpacking by spreading on the cutting table like lay and make it ply one by one.

Two types of methods to makes lay by spreading fabrics.

Manual methods

            Fully Hand Process
            This method is working by two people who are working from two different side of spreading table by hand or spreading fabric on the table by crossing a rod in to the tube in the center of roll of fabric. This spreading process a little slow and not so much finished and quality full.


            Hand process with hook
            This method also a part of manual process called hand process with hook because this process is a little different from hand process with a little extra material called hook. Which is made from iron and this tool looks like an English alphabet “J”. This method has a little advantage than hand process.

            Hand process with spreading track
            Spreading track is a special tool for hand process. Tracks carry the roll of fabric and spread on the spreading table by changing this position from front to the end of the spreading table. This method is working by two people who are working from two different side of spreading table by handling the track tools and spread the fabric on the table. The basic three condition of making a lay of fabric are not include in following manual methods.

Mechanical methods
            Semi Automatic
            Semi automatic machine is working almost similar to Hand process with spreading track process because this methods working technique and working prouder are same but this process are working by electric motor. A roll of fabric are installed in the machine like Hand process with spreading track and this roll are spreading on spreading table automatically. The spreading machine are running on the spreading table by from one side too another side by electrical and mechanical power.
The advantage of semi automatic machine
The machine has the ability automatically count the ply of fabric.
After cut the fabric the machine has the ability to catch the edge of fabric.
This machine has a special tool called inspection light which is check ant kind of fault in fabric.
To salvage alignment this machine has a photoelectric guide.
The machine has the ability automatically cut the ply of fabric.
The opening up of fabric from roll is positive & there is a regulator to adjustment the spreading and opening up fabric speed.
The facility to maintain the tension of fabric is including in this machine.
To make the surface plain has a toll are called leveling blade.
A platform is installed with the head of the machine for operator to seat and operate the machine.
This machine can spread three miter of fabric and this machine can carry from 80 KGs to 675 KGs.
This machine can spread 100 miter fabrics per minute.
25 CM lay can be makes by this machine.
When the spreading head moving without spreading any fabrics then it is can move a little faster than ever.

            Fully Automatic
            Fully automatic machine is upgrade version of Semi Automatic. This machine has the all of quality which is included in Semi Automatic. Full automatic machine has some special feature are makes it more special. Fully automatic machine is maintained by robot and micro processors. The additional advantage of fully automatic machine are given blew.

 This machine can be directed or fixes how many ply have to spread before start spreading.
This machine is working by robotic technique so if the fabric roll gone empty then this machine get another new roll automatically without any human power and start again spread where it was ended.
There is a sensor in front of head. This sensor marks the fault area of any fabric and automatically cut the fabric withy and stat again spreading.
Every type of fabric is able to spread and its can makes every type of lay.
This is automatic spreading machine so its can work so many faster then others spreading methods.

Definition of sewing machine



            By which machine used to sewing two or more pieces of fabric called sewing machine. A sewing machine sewing not only fabric, but also others material like bags, lather, foot-wear, tent & many more, Etc. sewing machine also used to increase the fabrics fineness and good looking by some special effect. Different sewing machine are obey there different duty to makes a better garments as we want.


List the type of sewing machine are used in textile industry
             
v     Manual operated sewing machine
Manual operated sewing machine is working by human hand or legs power. The machine operator’s have to operate the machine by his own hand or legs power so that operator can’t work so firstly and smoothly. As a result the manual operated sewing machine’s production is less than electrically operated sewing machine. Today most of the manual sewing machine used in home or a trailer shop because it’s not so expensive and it’s easy to maintenance and use.

v     Electrically operated sewing machine:
This kind of sewing machine working by electrical power, so it’s work first and smoothly. Comparatively electrical operated machine work and production so good than others so it’s called industrial sewing machine. Industrial sewing machine could be much type but some common types of machine are here.

ü      Lock stitch machine
ü      Chain stitch machine
ü      Over lock machine
ü      Zigzag stitch machine
ü      Flat lock machine
ü      Blind stitch machine
ü      Button holing machine
ü      Button attaching machine
ü      Bartech machine

Industrial machine could have one to four needles as required so that many industrial sewing machines presented company fill the importance. There are too many industrial sewing machine produce company around the world but most of this machine used in Bangladesh like Juki, Pegasus, Seruba, brother, Puf, Singer Etc. Every company make competition together there machines power, speed, efficiency, performances etc. the maximum used machine in Bangladesh is juki.

Some machine’s has programming so that it’s possible to make automatic sewing for any design or length what ever you want but this machine is expensive and so hard to maintenance. Though its makes better than others but usages in our country is so less.
